I /want/ to think of ltrace as an essential tool that I might need to reach
for at random times. Having it as part of standard seems to follow from the
idea that if you need it, it might matter to have it available for debugging
in cases where apt isn't working.
But having tested ltrace on impish and found that it doesn't work, it's
clear that the tool was completely non-functional for a full 6 months
without me noticing. Moreover, it's been non-functional for at least 6
months without anyone ELSE noticing and reporting a bug. Only when trying
to fix build failures in the package in jammy has anyone finally noticed it
So it's not so essential that we need to keep it around in standard.
And given that it's non-functional, I think it's fine to demote this to
universe without replacement in main. If you think latrace is appropriate
to support in main, then it's fine to put it through an MIR; but I don't
think it's feasible, or necessary, for this to be done before the 22.04 LTS
