My old dog experience has proven multiple times that staying with the main reference tool for the platform always pays out long term, as most forks or guest languages eventually fade out after the hype cycle is over.

The existing tools eventually get the features that actually matter, and I avoided rewriting stuff twice, on the meantime I gladly help some of those projects to backport into the reference tooling for the platform.

The only place I really haven't followed this approach was in regards to C++ in UNIX, which at first sight might feel I am contradicting myself, however many tend to forget C++ was born at Bell Labs, on the same building as UNIX folks were on, and CFront tooling was symbiotic with UNIX.
