If you can afford a custom ASIC, you can afford a top-end EDA package,
and a FAB that supports high-end features.  Frankly, PCB is not a
high-end package and custom ASIC users are not our target audience.

I can't afford any of that tech.  Heck, I can barely afford 4-layer
boards with 6/6 rules.  There's a huge community of designers that
can't (or won't) afford high tech features in their boards.

So you can say "this is factual" but it's not.  It may be a
requirement for a subset of our potential user base, but it's not
ridiculous to assume that many people just aren't going to use them.
Until we decide to support that tech, we're simply targetting the
"many people" who don't need them.
