I have been following this thread and agree with most of what has been said
.

What I find strange is that ATC did not issue an amended clearance or offer
a limited range of options. The last thing I would need if IFR amidst
convective cells would be to research a new route, propose it to ATC and
then hold somewhere while they decide if my new proposed flight plan is OK.
I find it rather bizarre that a pilot tooling along at 3 miles a minute is
asked to play "what am I thinking" with ATC who presumably knows where the
pilot wants to go and is in at least as good position to reccommend an
alternative route.
