The only way to fly!  :)
I've always done this, or a close variant.

In some apps, I've used a jump to a "halt and DONT catch fire" routine,
where the app controlled things that could easily get nasty if left on too
long. This routine safeties the outputs, and then sits in a loop.

My templates all have ISRs that turn off that particular int.  I start my
apps with this, and then change the ones I want to use into real ISRs, and
if I get squeezed for code space then I might change the turnoffs to simpler
versions, or to RETIs.

I dont' believe in EVER writing without a fully implemented vector table
though.
