I agree in general; some people might use version as a `real version,'
and others might use it just as a sequence number (I do this).
I don't think the term `version' is misleading though, and it seems as
good as anything.

This is completely arbitrary -- the version/sequence number of a branch
_may_ be related to the version/sequence of other branches, or it may
not (or more likely, it's related to _some_ other branches, but not
others).
If you use the version as a simple sequence number, I think it's much
more natural to think of it as a division of the branch (it doesn't even
really seem to make sense to think of `sequence 1' of the top-level
category).
Even when you use a convention like `--devo--VERS' where VERS is the
`real world' version, it's also completely arbitrary how you order the
two components: Is `devo' a branch within each release version, with
each new version having a new `devo' branch? Or is `devo' a long-lived
branch of the category, that has per-real-world-version divisions.

No, this is silly -- you're trying to assign a specific meaning to
versions, and the relationship between branches and versions. Arch
currently defines no such meaning or relationship, and it shouldn't
(as indeed you say in your first point!).
Morever, because the meaning of the version number is arbitrary,
different branches can use _different_ conventions -- e.g., I might use
the real-world version for my `release' branch, but a simple sequence
number for my `x' (experimental) branch. Given this, it would be
completely confusing if you put the version number first, as it would
imply some ordering among the numbers, when they are in fact unrelated!
For instance, if I have:
foo--devo--VERS : foo--devo--1.0, foo--devo--1.1
foo--release--VERS : foo--devo--1.0
foo--x--SEQ : foo--x--0, foo--x--1, foo--x--2
Under the current scheme you get this:
foo
foo--devo
foo--devo--1.0
foo--devo--1.1
foo--release
foo--release--1.0
foo--x
foo--x--0
foo--x--1
foo--x--2
This seems fairly straight-forward to me.
However, if arch were to use your scheme, you'd get:
foo
foo--0
foo--0--x
foo--1
foo--1--x
foo--1.0
foo--1.0--devo
foo--1.0--release
foo--1.1
foo--1.1--devo
foo--2
foo--2--x
Which seems quite muddled.

No, they don't. The current syntax is fine.
I basically agree with your first point, but that is at most something
to clarify in the documentation.
