I mean both as a development environment and as a runtime environment.

However, there may be an argument for treating VMS as an embedded
environment and hosting the cross compilers and associated toolchain
on another OS to do the actual development.

That would need the far tighter toolchain support (especially when
debugging multi-language environments) that the embedded world
expects as standard these days.

Especially given that I doubt you are going to be plugging a cable
from a JTAG adapter into a VMS system any time soon. :-)

I've built multiple gcc cross compilers over the years for bare metal
(ARM/MIPS/AVR/i386/MSP430) and for an RTOS (RTEMS) so yes, I do know
what can be involved...

All Linux hosted however, so at least that was something.
