But the fact that I have to use similar code anywhere I need to use spawnlp is not fair. Notice that spawnvpe is simply a clone of execvpe from os.py, maybe if the problem is new API in c source, this approach could be used in os.py?

Oddly, "fair" isn't a constraint in PEP-0006. Backwards and forwards compatibility between all point releases in a major release is. Adding it to os.py rather than C code doesn't make a difference.

P.S. Although it's a bit stretching, one might also say that implementing spawnp on windows is not actually a new feature, and rather is a bugfix for misfeature. Why every other platform can benefit from spawnp and only Windows can't? This just makes os.spawnp useless: it becomes unreliable and can't be used in portable code at all.

"One" might say that. I wouldn't. It stays out until 2.6.

Sorry Anthony
