When looking through the main EOTE rule book under the armor atrachments there are some that add skills to character as part of a modification. I have seen anything recently that adds skills from gear.

Do you think they found it too powerful to give? Or do you think with more talents available there were talents to match their intent better?

No, because:

1. Many of these are stacking talents, which usually require you to have several levels of to be particularly useful.

2. They're only available when the gear is equipped. Seems kinda obvious, but it can be hard to keep track of.

if my power armor gives me athletics 2 and I have athletics of 5 do I get an athletics of 7?

No. You cannot normally have any skills above rank 5 except with cybernetics, as stated on page 173 in the Core Rulebook.
