Dear max Alt
I agree with you.
It would be better to give you a hold meanwhile ATC could work and clear the Approaching flow.
It is their obligation to have WX radars giving them a clear picture on their screens, so they can plan ahead, and in fact even delay departures until that sector is clear.
WX must be avoided for the sake of flight safety.
I have the impression with the amount of traffic increasing constantly; it is possible that we are to suffer situations like you experienced, if proper measures are not taken.
Safe flying to all
