Found this thread when I tried to look for information regarding a personal license, and wanted to give my take:
The main issue is that it is hard to convince some managers, coworkers and companies. They ask about "value" and sometimes don't understand the answer. They see stacked branching and think "Well, that looks more complicated than just having one large feature branch". Sometimes it can be nearly impossible to get them out of that mindset.
In addition, some companies have very heavy processes for getting licenses where approval needs to go through committees and whatnot.
A personal plan would be easier for those that exists in organisations where change is difficult.
