Yes, I should have phrased this differently. Sorry.

I didn't mean to say that you weren't allowed to raise your concerns.
I meant to say that I think we shouldn't discourage Julian from
following down this path. I must have read a subtext in your comment
that wasn't actually there. Your comments are actually very valuable since
they prevent us from being mislead into a situation where subtree merging
stops working for users who are relying on it.

Agreed. Ideally, the symmetric merge will support all currently supported
use cases, without throwing errors at users or requiring new command-line
switches.

I haven't yet made up my mind about interim measures for 1.8 though.
I suppose if symmetric merge won't support all currently supported use cases
in 1.8, we could keep the --symmetric option in place for 1.8, and drop it
in 1.9 or later once the symmetric merge code can handle all use cases?
