The disposition of the regexp documentation could be improved, yes. Currently it's arranged by syntax, which is the implementor's view, rather than by function, which is the user's. Condensing related text into a single page would help. (Cf. the more recently written section on rx in Emacs 27.)

The manual does say

‘\{M,N\}’
     [...] If M is omitted, the minimum is 0; if N is omitted, there is no maximum.

so you may be mistaken on that point.

The \= anchor is probably less frequently used than the other zero-width assertions such as $, \< etc but does come in handy occasionally. It's there in case you need it.
