I do not remember details of the discussion about 'in' but I would like
to say that 'in' is quite important unit, especially for Americans.
We have to take into consideration that paper and other things are sold
in inches in the USA and it is not very comfortable to recalculate it to the
metric
system.
We can let it depend on the outcome of the elections and foreign
politics ... we can use the unit as bargain option (and Alan uses thise
french units anyway).
So I vote for keeping it forever, eg. till Americans will completely convert to
SI.
It was a joke (seems you didn't pay attention when arthur and I
discussed it the break ... we even mentioned 'meters' as possible units
and dropping cm and mm). Dropping nd and nc is because they were never
accepted as standard.
An inch is official tex and we're tex aren't we? But in luametatex the
inch is at the bottom of the scanned unit list .. you can guess the
order that we like most; scanning for in takes 25% more time than for mm
but only Idris will notice that (and when he used "truein" it will be
twice as slow).
