Excuse me?

{
  \transpose es d { \key f \major s1 }
  \transpose es eses { \key f \major s1 }
}

LilyPond has no qualms about things getting weird.  The typesetting
stage will bomb out at more than _double_ accidentals (slated to be
changed IIRC), but processing will proceed just fine.  Try
\transpose e feses here.

There have been a few proposals for the sake of transposing instrument
transpositions about weirdness limiting methods, but nothing with
permanent impact so far.
