they also all ded, is cannon, opaline is the last living alicorn, and she ebil, she made them alaaaaaal ded

so maybe he became alicorn...but it no mater, cause opaline unalived him, either directly or by stealing the magic sustaining them to sustain her own life while the rest of equestria was bereft of it.

No matter what anyone says I believe Shining Armor became a ailcorn along with Cadence

I guess someone agrees with you. https://www.fimfiction.net/story/478175/armor-gleaming-bright

Truth be told with gen 5 I just started to think it ran in one of the timeline made with time travel due to like twilight’s time loop or starlight time travel shenanigans so there can be a time line of a happy crystal royal family.

Another question I have is if the crystal empire is mentioned or shown in the lore of gen 5?

There was this really good fanfic called Together Forever where he becomes a ailcorn after Cadence arguing with Celestia about it

And I agree yes that Gen 5 is a alternate timeline.
