My answer is no. I'm running CM, and I cannot see any reason to upgrade. All the developers (Pete, Koush, AdamZ, Chevy, etc) will be moving the 2.1 features into the new roms, so there is no reason to upgrade.
Just wait for the next ROM upgrade for your respective ROM, that should be the Droid ESE81 build, with all the rooted features.
Long story short: just wait a week, you'll get an update to your current ROM.
