The Browser, yes. But not the components doing the WPA stuff:

Only recompiling openssl with TLS1.0 and TLS1.1 enabled allowed my phone
to connect successfully.

It is far more than 25%. Lollipop, Kitkat and Jelly Bean add up to ~52%
of marketshare and I don't think this number will drop significantly
below 25% in the next 2 to 3 years.
