I would appreciate it if you would please use a more respectful tone
when communicating regarding these issues, so everyone feels safe and
welcome to participate in the discussion.

I understand that Docker is not going to be available for every possible
host platform, and, one of the most important ideas here is that no
person would be performing manual compilation of ScummVM, except during
development or updating of the worker images, so it would not be
relevant in the future that you have historically used a non-x86_64
platform for building these releases as humans would no longer be
responsible for building the official releases in this manner. If you do
not have an x86_64 computer, I would be happy to find you an inexpensive
used one so you may use the prebuilt images from Docker Hub, if you have
a concern about some difference between GCC running on platform X versus
on x86_64.

If you believe that there is a need to hand-split and add curated demos,
then simply update the Dockerfile and/or buildbot.cfg for the Dreamcast
worker with these changes whenever it is time to adjust the split or the
demos. Then the automated builder is up-to-date and the release process
can continue to be fully automated and maintained by other team members
whenever you are no longer available to do so. There is no need to make
an exception for a manual release process for this kind of thing.

Best,
