ISP's allocate address blocks to 1000's of commercial clients.
Finding a new 6rd prefix for a new IPv4 allocation is no harder
that finding a address block for a commercial client.  In fact it
is easier as you can (but it would not be desirable) create multiple
prefixes if you find there is not a existing block that is big
enough.

If ISP's can support 1000's of commercial client address blockss
they can support 100's of 6rd prefixes.
