Seemed to work fine for me... I'm now trying to install both versions of brew and spin up terminal sessions accordingly.

Are these 'good practices' for Arm Macs?:

1) When spinning up an iTerm session, figure out if it's 'Darwin x86_64' or 'Darwin arm64' - and configure paths accordingly. so they use the right brew binaries.

2) Easily double check what version of a running package/keg based on what arch is displayed in Activity Monitor.

3) That way, you can just use brew with Rosetta to start (which I did) then build up native arm Brew over time. and let the Rosetta brew fall away.
