[jg]Ah so, they're not cutting themselves out of widest
consideration of simulation for generic parts, just the
system-mostly-on-chip parts.  The logic must be, "If you
have decided to pay for our system-mostly-on-chip parts,
there's not much to design, so you can afford to be limited
by using only switchercad.

This implies "the weeds" from
their perspective are other brands of system-mostly-on-chip parts,
they don't contribute much "organic matter"
and we are beneath being their "beneficial insects" even.

but clearly they think
