If I am not pressed for an immediate deadline I could modify core in my current project as a proof of concept and if it works I'd like to be able make a patch for core from there (and then issue a rollback since I can't deliver code to clients that depend on a patched core.)  But I can't do it this way.

I have to recreate the data environment including what relevant plugins are currently installed needed for testing this issue in trunk (which sadly my development project's database already has.) That can take from 5 minutes or more than an hour, depending. Now I have to go find all my changes and reapply them to trunk. That can take 5 minutes, or longer than an hour, depending.  After finally getting the idea implemented in the latest version of trunk only then can I make the patch. But since I don't work in trunk like you usually do, this is typically something that I can't devote the time to because its unknown to me how long it will take and my subsequent client deadline pressures.

How is switching VCS going to magically make it easier.

You still have the same base issue - you are rightly developing a site using the current stable release but want to patch against trunk.

You are still going to have to switch your code over to another checkout and test there?

In the situation you describe my process would be as follows:

1) Find bug in stable WordPress while developing client site
2) Search trac for bug reports - find nothing carry on. Find fix - apply and test out.
3) Submit trac ticket for bug
4) Create fix for bug in Stable WordPress
5) Submit patch to trac ticket against stable release.

You don't need to setup a new site or anything the checkout you have is a good place to work

In some cases your patch will apply to trunk too anyway - in other cases merging it into trunk will require some effort.
