https://en.bitcoin.it/wiki/Getblocktemplate is supposed to solve most
of the pooling-centralization problems. Unfortunately, it is opt-in,
and GHash.io doesn't support it.
Also most miners don't care and don't do the work to set it up. To do
transaction inclusion themselves, they'd need to run a full node,
which is a bit more work and resources than just pointing hashpower at
a stratum server.
If you figure out a way to make GBT widely used (>50% hashpower), kudos to you.
