Thanks for pointing these out.

The 3bot warning is present even if I remove my explicit use of it from
foo.tbl;  I think tbl's at fault for not initialising it and all tables
generate it?

Similarly

    $ sed 5q foo.tr
    .if !\n(.g .ab GNU tbl requires GNU troff.
    .if !dTS .ds TS
    .if !dTE .ds TE
    .lf 1 foo.tbl
    .\" set -eu
    $ 

Should tbl not have a conditional .ds T& to match the TS and TE?

The real-life example is more like

    1  mulberry finalized spoilage
    1  pores bathrobe's simplified
    1  subsidization's
    1
    1  synopsizes astrakhan's virility
    1  corsets Uranus's extramarital       1,111.11

    2  integrates cachet's morpheming      2,222.22

    3  Csonka Morrison's
    3
    3  plectrums
    3
    3  tunic Chartres circumference's
    3  multiples
    3
    3  Feynman's Bacall's privileging
    3  mural's Secretariat's stockaded      3,333.33

where the amount is for the item it's level with the bottom of and all
preceding items since the previous amount, as shown by the leading
digits which wouldn't normally be present.  So vertically centred would
be harder to parse.

True, but it's part of a bigger document and I'd have to make it
conditional on the device so the PDF still triggers the footer.  Plus
`cat -s' squeezes multiple blank lines everywhere, not just the trailing
ones.

Cheers, Ralph.
