The standard way to attach something to a bar line is to typeset it as a
text mark (see section "Text marks" in the manual), i.e. to use the \mark
command, which not only can be used for rehearsal marks, but for anything
you want attached to a bar line. This solves the first item on your
list of
examples. However, there are some limitations:
- The text marks are only typeset over the top stave of the score by
default,
which makes sense if you have connected bar lines between the different
staves of a score. See "Text marks" for instructions on how to modify
this
behaviour.
- You cannot start or stop "spanners", i.e. things like crescendi,
pedaling,
text spanners this way. However, for crescendi, you can use the
hairpinToBarline property, see section "Dynamics".
Regarding the possibility to sponsor the implementation of new
features, it seems
that none of the main LilyPond hackers have the time to do anything
like that
for the moment. We have a long list of bugs, that also needs to be
considered,
for example.

Hi,
Something I often want to be able to do is to attach a notational
element to a barline. For example:
|\fermata - place a fermata over a barline
|\! - end a (de)crescendo at a barline
|\sustainUp - end pedalling at a barline
|\stopTextSpan - end a text spanner over a barline
What would the estmated implementation difficulty and sponsorhip cost be
for this?
Many thanks,
Jamie
