Why make so much work for yourself? It means that every time a new
bug needs to be fixed in the branch, you need to a whole bunch of
extra things: create "temporary" branch from a tag, copy the changed
branch back to a tag, and then destroy the temporary branch.

That's a whole lot of unnecessary busywork. Wouldn't it be easier
just to keep the 1.0 branch up and running all the time?

There's nothing special about tags. They're just branches ("snapshots
in time") that you never commit changes to. They're useful as
reminders, but you're not compelled to use them.

For example, we could have created a tag for each release of
Subversion. We actually started down that path, and then said, "nah,
why bother? If I look in our CHANGES file, I just *know* that release
0.12.0 was r1868 of /trunk). So we're not using tags at all right

It's funny really.... when Jim Blandy designed this system, he was
hoping that we could eventually do away with the terms "branch" and
"tag" altogether. In Subversion, we only have a single idea:
"copies". The only reason we keep talking about branches and tags is
because we're trying to get CVS users to understand how to make SVN do
what they're used to.
