A "design" may be new but one may have hardware or software modules that
are tried and true from other designs. Not limited to assemblers,
compilers, and debuggers.

If one already buys 8051's for another project it doesn't make much
sense to add yet another purchase item to the corporate inventory unless
the 8051's are proving inadequate..

AVR is single-sourced from Atmel. 8051 clones come from many different
sources (including Atmel), in many different configurations.

Cost. Is possible that an 8051 costs less than an AVR. Depends on a lot
of parameters.

Radiation hardening. If you need it, its not optional.
