This is a good point… While I don’t think it’s necessary to update everything every 2-3 days, it is important to update regularly at the moment. ESH, which forms the core of OH2, gets updated when there’s important changes, and when it’s considered to be reasonably stable. That is roughly every week I would say.
The reason I comment on this at the moment is that HABmin is using some features that are only available in the latest branch of ESH, so you need to be running an OH2 build after the 2nd March or you may find a few issues (eg saving items might fail).
For updating, I’m personally using a slightly modified version of the script from @xsnrg as described here -:
