This applies to Mew, Celebi, Jirachi, Deoxys, and many others. It doesn't matter if they offer new ways to obtain them in the future.
Furthermore, Ash-Greninja is considered Mythical because it was forbidden by the rules.
On the other hand, Therian forms, Blaziken's Mega Stone, Walking Wake, or Rotom's forms, despite their initially limited availability, have never been mythical, nor considered as such. Even if their initial appearances resembled distributions.
