So I like this approach but fear it causes bloat in terms of size of the template when compiled and pushes you towards that 4mb limit… Thoughts?

It’s definitely a consideration. Especially as I only use AVM now so I usually stray close to the 4mb because of that anyway. Nice to have the option in the repo I think. Even if I only use it to find the guid in my workflow quicker vs pattern load in. Vs leaving code and going on a manhunt on azgov

Please DM a correlation ID if you hit the 4mb limit and a timestamp. I’m looking into this further atm 👍

I think there is a GitHub roadmap item for bicep team to get a similar feature built in. although, not sure that would fix the potential limit concerns or just give users an easy func to call on for each role guid. if so that would work better and make this obsolete which would be neat
