I think it is excellent that a LEO constellation can be upgraded that 
fast.  It means there will be an ever improved service to end users.  
This reliable launch frequency, orbiting, de-orbiting, are extraordinary 
technical achievements.

However, as with everything, one should also think about the 
inconvenients.  It can't simply be a win-win-win, without someone to 
loose something.

Probably one of the inconvenients is the additional risks involved by 
re-entry, new collision avoidance necessities, and sky observation 
blockage.  There is also the risk of some unwanted collision hapening up 
there but deemed as wanted by some.  It is new unknowns - says a 
non-expert -  that we add to the already shaky overall system.  They 
should not be overlooked.

True too:  probably it is the technology too that might help alleviate 
these potential problems (if problems they are), and not the lack of 
technology.
