I have a ROM for your cartridge port: It gives You a NULL at any byte, word or
longword adress... 8-)

[Hmm, get serious Hartmut!]

It is difficult to operate a math chip without writing to it; writing to
the ROM port is tricky (but possible..).

It would be possible to make a cartridge with a 68 881 or anything like
it. But the chip ist expensive and is it worth the effort?
Atari did a great job in building obstacles to math chip use (they used
the reserved F-Traps for operating system calls instead of math chip
acces). The chip can only be used as some kind of a weird peripheral.
The application must now about it, not just the operating system:
everything must be recompiled....

Everything that *could* be done in hardware (like number crunching,
memory management, disk or other I/O) *must(!)* be managed by the
operating system (look at the Macs floating point lib) not by the
application or compiler (like the 8087/80287/80387 in Mama Blues
machines).

There will be no standard for the ST, right?
