In theory there isn't necessarily anything wrong with this idea... But 
in practice JUNOS-ES is still very buggy and can't be turned into a 
complete replacement for the original JUNOS on the J-series. People 
don't like it when a product that they bought for a certain purpose gets 
pulled out from under them with no workaround or compensation, that 
seems to be the bottom line point that Juniper is missing. Adding a 
mechanism to reduce the memory consumption when you turn off flow mode 
seems to be the least they could do to make it right, and not "that" 
difficult.

Of course it would have been nice if they had at least left the last 
working code of the old version in a reasonable state too. 9.3 on 
J-series is a complete mess, and the last semi-stable version (8.5) 
doesn't have support for 32-bit ASNs. Obviously engineering resources 
and support for every old product has to come to an end eventually, but 
IMHO Juniper really screwed the pooch by leaving the last working code 
in an unusable state before abandoning it.
