The question here is, why make a difference between "legacy" clients and
clients with support? Why hide that an action was performed from users
with supporting clients and show that an action was performed to users
of "legacy" clients?

This mixes things up I think. Messages that are triggered by an action
are always visible as such, because they contain an <action-selected>
element. Messages that are triggered by a quick response are not meant
to be anyhow differentiable from manually types messages.

Why do you want to know? In the example of a merge request it does not
matter at all, the action is just a quicker/more convenient way to
trigger the merge request in exactly the same way that would be possible
via the web interface. The bot could also just add "triggered by ..." to
its merge notification. Can you construct a scenario where this is
Thing is, if the bot defines the body to print when an action is
selected, the bot can just as well just print that message itself when
the action is performed. Take the following two options:
*marvin selects action*
marvin> /Merge MR!3
gitbot> MR!3 merged
*marvin selects action*
gitbot> marvin triggered the merge of MR!3
I don't see how the first variant would be superior to the second, keep
in mind that in both cases the bot fully controls what is printed, in
the first variant by setting the "fallback" body and in the second
variant by printing it directly.

Hehe true, simple polls could be handled with thumbs up or thumbs down
reactions, but polls with more options would require mapping emojis to
options etc. :D A poll bot could obviously offer more functionality,
like limiting the time for votes, printing cool summaries or even doing
stuff based on the result of the vote.

Quick Responses are restricted to the last received message with a MUST,
because there is no way to relate a response to the original message. I
think this question is rather general actually: how to handle if
multiple bots ask questions that require plaintext responses? Keep in
mind that quick responses are just plaintext messages you could've
written manually, no magic. So this problem isn't actually a problem of
quick responses, but the general problem of how to do questions/answers

That's missing, right. Could be as easy as referencing the MUC-jid of
the bot in the <action-selected> element. I'll think about it.

Splitting this into two protoXEPs has been proposed by Dave and I also
feel like it should be split. The two features are pretty much
independent, even though they solve "similar" issues that probably both
come up when implementing bots.
Regarding forms there also was some input by Dave. If actions can be
done with forms without much struggle I'll change actions to use forms
instead. Though I think that actions as they are now are so extremely
simple that it might not be worth to pull in forms. We'll see though,
I'm open to the possibility.
