The code path executor -> PL function -> SPI certainly works, so
presumably omitting the intermediate PL function could still work.
Whether it's a good idea is another question entirely.  I do not
offhand see a good reason why knowledge of non-system tables should
exist in the core executor; so what is the need to use SPI?
