His completion style relies on an advice to the completing-read code
which re-adds the text that was stripped during the completion.
Clearly, that won't work when used for completion-at-point.
I actually think his approach is interesting and maybe we should think
how our completion system could provide support for these kinds of
"styles".

Indeed, an important design constraint I followed for the completion
styles is that the user should be able to choose the style (hence the
indirection through completion-category-overrides).
I think part of Stephen's argument is that the same comment applies to
the new completion behavior of M-x project-find-file you installed
in 8f9d93f3054.

I'm not sure if it currently can work for any project backend, but its
design definitely aims for it to be backend-agnostic so it can be used
for any (flat) completion table (I don't think it'll work well with
completion-file-name-table).
