Is there any chance of finally switching the pkg abi identifiers to just
be uname -p?

Keeping asking won't make it happen, I have explained a large number of time
why it
happened, why it is not easy for compatibility and why uname -p is still not
representing the ABI we do support, and what flexibility we need that the
current string offers to us.
if one is willing to do the work, please be my guess, just dig into the archives
and join the pkg development otherwise: no it won't happen before a while
because we have way too much work on the todo and this item is stored at the
very end of this todo.

I'm happy to do the work, and have volunteered now many times. If uname
-p does not describe the ABI fully, then uname -p needs changes on the
relevant platforms. Which are they? What extra flexibility does the
string give you if uname -p describes the ABI completely?
-Nathan
just simple examples in armv6:
- eabi vs oabi
OABI is almost entirely dead, and will be entirely dead soon.
- The different float abi (even if only one is supported for now others are
being worked on)
armv6 and armv6hf
- little endian vs big endian
armv6 and armv6eb (though I think armv6eb support in general has been
removed from the tree, but armeb is still there)
These all already exist.
the extras flexibilit is being able to say this binary do support freebsd i386
and amd64 in one key, freebsd:9:x86:*, or or all arches freebsd:10:*
The second one already would work, wouldn't it? Just replacing x86:64
with amd64 won't change anything. The first has to be outweighed by
being able to reliably figure out where to fetch from without a lookup
table.
We also added the kern.supported_archs sysctl last year to all branches
to enable figuring out which architectures a given running kernel
supports (e.g. amd64 and i386 on most amd64 systems). This was designed
specifically to help pkg figure out what packages it can install.
