Greetings My Dear Chicar -
This is a most excellent topic and insight!
...
i would became by defining science-fiction and explain how it is not only a technological businness but a general scientific one. Preternatural things like cryptids, zombie viruses,clarkian magic, superorganisms (eldtrich beings) and psychic powers are as much worthy to be call sci-fi elements than robots and spaceships.
Than i would end by saying than steampunk is sci-fi based either between the french revolution and the end of WWI or in a setting ressembling this time period.
...
Well Done, Sir!
Steampunk is most certainly an "alternate Reality" and I very much agree with the "Preternatural things" ...
I am also enchanted with with your time setting:
"between the french revolution and the end of WWI or in a setting ressembling this time period. "This covers an excellent time period which is chock-full of intriguing events and the opportunities for many
"what if" forks of alternative history! The era itself reeks of Collonialism ( with both it's ups and downs and terrible acts),
The Industrial Revolution ( ditto ) and the various Cultural Revolutions (ditto again) going on throughout the world, as
the common folk took hold of their own lives, fortunes, and futures... wrenching them away from the Aristocracy.
I recently learned of a term would may help me with this explainations in the futur: Novum, mainly what out of the ordinary but still scientificly rationalisable.
https://en.wikipedia.org/wiki/NovumIt has the merit to give a wide enought definition of sci-fi to give a wide enought definition of steampunk to please every tastes.
To elaborate on this, I will quote snips:
For those of us who are Latin Impaired:
snip-----------------------------------
Novum (Latin for new thing)
.....

Suvin argues that the genre of Science Fiction is distinguished from Fantasy by the story being driven by a novum validated by logic he calls cognitive estrangement. This means that the hypothetical "new thing" which the story is about can be imagined to exist by scientific means rather than by magic, i.e., by the factual reporting of fictions and by relating them in a plausible way to reality.[1]

I personally agree that "Preternatural things" need to be included in parallel with alternative science, but separate from the "fantasy/ magic" bit... otherwise we have Gandalf and Unicorns running into Capt Nemo and Sherlock Holmes and it gets
way to messy for my palate.
However, 2 excellent examples of "Preternatural things" that most folk consider Steamy would be the Hellboy and the newer Sherlock Holmes movies.
Additionally, I agree it is important to include the "supernatural" because at any given point in time, the Science of the Era
cannot explain all events and abilities.
Even in this modern age there are abilities and events that scientific methods can't yet explain.
