Switching to User Manager quesions

We are currently using RadiusManager and are looking a the possibility to switch to User Manager. Before we make a switch, what is the development status on it, ex is it being maintained and updated or is it in limbo like Dude? How many users can it support? Does it support Access Lists, and if so, does it support other equipment such as Ubiquity? Can users be enabled/disabled via cli?

Thanks for any info.
