@rxin In your case think it's better to have this turned on by default.
Regarding your other questions:
1 - There's no timeline. 2.2.x will come out when new features are
requested by our users and implemented. Currently there's nothing in the
pipeline so we'll be on 2.1.x adding fixes and minor internal improvements over
time. We have no open bugs either.
2 - Yes. It fixes a couple of bugs you guys probably won't come across, but
it also improves the performance of the parser with whitespace trimming enabled
(it's enabled by default, by the way).
3 - It's OK and I don't see why it would be a problem, other than having
some client with a very uncommon use case (they are out there, that's why the
library has a lot of configuration options).
