Tailor does not know anything about branches, and has a very limited
support for tags. This comes from the fact that tailor was born to
migrate changesets between /different/ kind of VCS, and thus it
supports only those operations making sense on both ends: "history
preserving copy" is available only on Subversion, while on most modern
DVCS that's just a "branch".

Sorry, I do not understand the question, and in particular the
"destructive" use of rsync...

Tailor did/does a great job for me, with exactly that goal, but I'm
mostly using it to migrate "vendor code" to my own set of darcs
repositories from whatever system "vendor" used. For my purposes, I
usually track just a single line of development at a time (that is, I
usually do not convert the whole upstream SVN repository with /trunk,
/branches and /tags, but rather just /trunk, or just
/branches/the-interesting-one).

That's what tailor actually does, more or less.
