One thing to keep in mind is that whether one creates microbranches or
not, etc. is sort of a client issue. The server can store them
efficiently; the protocol lets you create them efficiently; what
features you provide with those facilities is up to the client.

One of the (unstated?) goals in Subversion was to keep the server's
semantics very simple, and push as much as possible into the clients.
It's much easier to experiment with new features on the client side:

- client-side bugs alone can't compromise the history on the server,
  since there are no protocol requests that modify history (that's
  still true, right?), and

- unlike the server, clients don't have to be shared by all the
  developers on a project: one person can try out his own stuff
  without inconveniencing everyone else.
