Sort of, While Keke Gekai Jutsus are not ranked, Jutsus from those clans, as the Nara and Akimichi, are ranked.

Besides none of this clans has ever been told that have any special trait.

For example it was stated that the 3rd hokage knew about all jutsu of the leaf village, but against Orochimaru he didn't use for example the shadow bind jutsu to bind Orochimaru while he extracts his soul with the death god jutsu.

That’s circumstantial, Kakashi knows 1000 Jutsu, yet we have seen some 12 Jutsu form him.

Its not really a Bloodline, If I remember correctly, at birth they are given the bugs, so the bugs live in the body of the person as if their body was a nest. This people use their Chakra to feed these bugs.

And the Third Hokage seems like someone who would respect the autonomy of the Konoha clans and allow them to keep how they use their jutsu secret.

I personally believe he knew ALL of the Jutsu from Konoha, including those from the clan.

The Sharingan only copies the movement and allows the user to perfectly duplicate what they saw. A sharingan user could copy a taijutsu, genjutsu, or ninjutsu technique based either on the handseals or movement of the body.

The Sharingan does not only uses the movement copying to copy a jutsu, if it where like that, someone with the Naked eye could also copy a Jutsu, the Sharingan analyzes specifically the inner Chakra working, this help the eye to magically pass this info to the person and thus (barring any physical incapacity) been able to perform it right away, for example on how Kakashi copied Zabuza Mitzu bushin, whereas Zabuza did not performed any Handseals.

But the clan techniques are different which is why they are only useful to members of that specific clan. Someone like Itachi, Kakashi, Sauske couldn't copy what a Shino or Kiba do. Their clan techniques are brought about by the bonds they make with animal or insect helpers. A sharingan user couldn't use Choji's clan justu because of the massive amount of calories the Akimichi convert into chakra.

Incorrect, Itachi or Sasuke or Kakashi or Madara, can copy any Jutsu with the Sharingan, the problem lies in been able to execute the Jutsu given those constraint you mentioned.

And a sharingan user couldn't either use Shikamaru or Ino's clan jutsus. Notice how Shikamaru and Ino and only use one handseal and they hold it during the jutsu? They don't follow the typical horse, dragon, tiger, ox, rat..etc seals for jutsu. So there is nothing to copy.

Incorrect, as I explained, just because it doesn’t require Handseals, doesn’t mean it can’t be copied by the Sharingan.

The secret isn't in the movement. It's in how they manipulate yan & yang chakra. In order to manipulate your shadow or take over someone's mind, you need to learn a very specific type of technique and can only master it through training and having a clan member teach it to you. So there is no sharingan shortcut for the secret clans techniques. And the clans guard their techniques with their lives and don't teach outsiders.

I find interesting the degree of information you have about Ying & Yang Manipulation when the author only mentioned it superficially once.
