Well.. I think when games end with 1.0 it means it's completed and devs finished to work on it
If there are games getting additional content later on then it will be announced, I guess
Revision number are not normed and are in no mean to behave like normale, numerical numbers. Often they use a schema with x.y.z, where the z is normaly used for patch only, y for minor updates (who doesn't break anything) and x for major update (who can break something).
x, y, z are natural number and the each version number only been used once. Additionaly if the version number gets an update it is one of this case:
- (x+1). 0.0
- x.(y+1).0
- x.y.(z+1)
But this is only for the common use of the x.y.z version number, that also is not normed. What the dev use and how they use is up to the dev and sometimes even a dev don't know a it. It is, to my knowledge, nonewhere defined that a 1.0.0 is a final product. Often it is the first avaiable version for consumer, yet the whole we release a software that is in devolopment had an inpact on this.
So disscusion about version number and how they behave have, from my knowledge, never done anything other than introducing madness.
Most games end with version 1.00, are there any incest games that still receive updates past 1.00?
Sisterly lust is at 1.1.4, although all above 1.0.0 is mostly bug fixing and not additional content.
Also you can look yourself:

A first glance show a few incest tagged games that are past "1.0", but I wouldn't give much about this revision number in the first place.
