Yes, but let's please not make network design decisions based on the =
limitations built into one of the cheapest routers on the market =
intended for the lowest of the lowest common denominators.
There are many other examples of CPE that can make use of properly sized =
prefixes (/48 per end site) and there is no reason not to deploy these.
I find the /50 particularly odd as it's not a nibble boundary and very =
close to /48. It's almost certain this is an operator who fails to grasp =
that they could have easily gotten a larger allocation from their RIR if =
they just asked for it and provided the appropriate justification in =
terms of giving /48s to their customers. OTOH, it's far better than =
those ridiculous providers that are screwing over their customers with =
/56s or even worse, /60s.
Sad, really.
