That'd be great, thanks.

For starters, it's Labor Day weekend...  For finishers, no
comment is in fact a really good argument for *not* putting it in.
If the idea seems good, people will pipe in with "+1, sounds good".

Broadly speaking, Trinidad is rather conservative w/regard to
adding new components.  This is a *good thing*.  Saying "no"
is one of the most important things that any open-source project
can do to keep its focus.  This is particularly important for
a project like Trinidad where we make every possible effort
to avoid any backwards-incompatible API changes going forward.

That said, for component contributions we should:
  - Look for alternative implementations - can this be done some other way?
  - Review the name of the component and name of any new attributes
  - Make sure the community agrees it's generally useful

Lack of consensus (much less lack of any comments) means "don't
put it in (yet)".

BTW, this also goes for new public APIs:  adding an API to
RequestContext with no public discussion isn't a great thing either.

I've given you an alternative more than once!  For starters,
the idea that end users should need to add any component
at all, or set a single attribute at all, just to get their server-side
messages to show up is not good.  The fact that they don't
show up correctly today is *a bug*, and one that should get

That statement needs justification;  and, if we fix server-side
messages, then it is certainly the case that the benefit of these
new components appears to be greatly reduced.
