First there’s the “text” definition, then treesit-forward-sentence uses it as a 
heuristic to get better results in comments and strings, rather than the other 
way around. So for me it doesn’t make much sense to say if “text” is good or 
bad name for treesit-forward-sentence—it’s not for treesit-forward-sentence to 
start with.

My suggestion would be for both treesit-forward-sentence and -sexp to use 
“text” for their heuristic. If someone wants more customized behavior, they can 
always write a custom forward-sentence/sexp function.
