What kernel would a modern DamnSmallLinux use?

I am asking out of curiosity, I haven't kept up with Linux developments in general, but I do remember reading somewhere that kernel version 2.6 was "too big" for DSL and that some of its improvements were backported into 2.4.

Newest kernel version is 6 and I doubt it would fit within the 50 MB constraints, so if DSL were to come back to life, what (versions of) software do you think it would use?
