Did you miss the part where I said it would make it much easier to experiment with it if the build system was better? For example, switching between different networking implementations can require a rebuild.

SIMH improves quickly enough that you won't want to do a 20 minute build every 3-12 months, but instead perform new builds with some regularity.

Between that and ease of experimenting (or the lack thereof) a bad build system can really hold back a project.
