That's why the default mode-line would have a text property on the parts
that are likely to ligate.
e.g. if my mode-line reads like:
-:--- foo.c All L1 (C Abbrev)
Then we'd apply this text property on the "-:---" part.

What do you mean by "this part" specifically? The part where we call
into Lisp for any character in `composition-function-table'? Or the fact
that we do a regex match each time?

Of course. By OOTB (out-of-the-box) I meant reading the GSUB table so we
can apply ligatures *without* requiring manual configuration. i.e.
making the shaping engine do the heavy lifting.
Are we OK with the status quo then, where ligatures have to be manually
configured? In that case, I could send a patch to remove that item from
etc/TODO.
