That's a lot of possibilities, but I'm lost how to get started: what
tack would I have to take to subordinate accounts?

Thanks, that's quite clear - I'd use only credit limits, not
allocations for the catch-all, which never expire, and thus are
considered last. Other accounts in a Project (= Department) are user-
exclusive, thus 'more specific first' is what effectively occurs,
which is *perfect* for the organization I have in mind.

Thanks! - I found that I user accounts U<n> need "-u user"; otherwise,
"gbalance -u user" and "glsaccount -u user" list *all* accounts in the
"user" or "staff" project, not just the catch-all and the user's own,
and reservations/charges go against the time-selected account, which
would mostly be that of the wrong user.
Actually, I started with already existing user-specific accounts and
projects and migrated the accounts like this:
gchaccount --addUsers U1 --delUsers MEMBERS --addProjects users -
After prior reservations are expired, I'll do:

Not even sure if I need hierarchies. I can now do:
gbalance -p staff
gbalance -p user
Those act basically as filters to distinguish the two people groups,
which have different privileges and reporting requirements. There is
no "total" row, but that is trivial to compute when needed for reports.
This does the right thing, showing only (1) the personal account, (2)
the users or staff account, and (3) any proposal-based accounts/
gbalance -u <username>
is not as long as it used to be, and contains only users, staff, and
proposal-based projects (those have -u MEMBERS, and "gusage" works
well there.) The output of "glsproject" is *wide* because of the
Users column for projects "users" and "staff" is, but that's not a
problem as it can be suppressed using --show.
I'll watch the logs and transactions. I have long jobs with a low
turnover rate, but things look good so far.
With best regards,
