In my experience, among the packages that have to display something (as
opposed to your usual major-mode which only provides commands to
navigate and edit text), very few correctly deal with all possible
`display-buffer-alist` customizations.  The vast majority assumes
a single-frame setup and break in random way in less
conventional situations.

So if transient.el misbehaves in some of those cases, it's in pretty
good company.

In the transient.el API the only thing that could inherently cause
problem, AFAICT is the fact that it relies on being able to
display a "sizeable" amount of information to the user, but it's hard to
imagine a comparable feature that doesn't make similar assumptions, and
it's hard to imagine a situation where there's really no way to make
it work.

So any problem it might suffer should be a mere "implementation issue"
that can be fixed without impacting the packages which rely on it.
