*Technically* the only issue I know of is that last time I looked PCRE was
much less optimised than grep (partly because PCRE is more general) so
searching a big tree of big files may be noticeably slower.

But this is more code that needs to be written, debugged and maintained.
 Pull requests (with an ongoing support pledge) are welcome.

The benefits of control and consistency (and as you pointed out on IRC to
search the buffers not the files for open documents) may not outweigh the
cost of doing it.
