[gemlist] is not a replacement for [repeat] nor vice-versa.

It's just in certain contexts, that you can use one instead of the other. 
For example, for your fractal creation using [gemlist], you do it 
depth-first with small polygons, whereas the way I constructed my polygon 
was breadth-first as one big polygon using something like [repeat]. (There 
are also depth-first ways of constructing one large polygon, and 
breadth-first ways of constructing small polygons).

Overall, [gemlist] is only for making exact copies of something ("exact" 
as in they only differ by a change of coords: translate, rotate, ...), 
whereas [repeat] can be used to produce any sequences of vertices using 
counters, [expr] or whatever else. My use of [gf/gl] is a direct 
equivalent of using [repeat] with a counter to iterate through a table 
using [tabread].
