Ok, thanks Martin/guys...

So, the short answer is:

"Don't worry about it, if/when something needs to be done to prevent
breakage, we will let you know ahead of time via a news item or other
appropriate method."

Which sounds like the right thing to do for those of us who prefer
stability to (too much) bleeding edge?

But - for those of us who, while preferring stability, also might like
to get a jump on things *if* switching to repos.conf now is:

 a) easy,
 b) fully supported, and
 c) considered perfectly stable,

would it be possible for someone with intimate knowledge of the details
to write up a wiki page for how to go about it?

Thanks again!
