Deleting and recreating definitely has its advantages.

The "diskid..." nodes incorporate drive make, model, and serial number,
which is appealing because the node name is machine-generated
(precluding typographic errors), unique, and matches the physical label
on the drive. This is probably the best answer if you have a lot of
disks. So (see ):
# zpool replace wd ada3 diskid/DISK-WD-WCC...
But deleting the pool and starting over gives you the opportunity to
create and use human-friendly labels. I have a dozen or so data and
backup disks, and I use GPT with labels.
It is nice to have multiple good options. :-)

A networked version control system is very useful for system
administration, among other things. I don't know how people get by
My CVS repository is in a jail on my SOHO server, along side a jail for
Samba. Every time I work on that machine, I lose CVS support. I have
contemplated moving CVS to my old laptop for just this reason. But what
I really want is to configure another server identically and set up HA
for both services.

YW. I'm glad it worked out. :-)
