Reasons for romancable companions with lower levels of polish on their content:
Karlach was the last companion done. Not even having a unique character model until release.
Minthara was intended to be evil route only.
Wyll’s personality and story was completely rewritten during EA.
Halsin was shoehorned in as a companion due to request of some EA players.

Shart, LZ, Astarion and Gale are all more or less complete.
