Go player here for input: The common speculation among that community is that TPC wants more shiny Mythicals available as options.
Go Tour once-a-year often makes one of its selling points a "Boosted Feature" Ticket you can buy, and one of the Perks for that is a Special Research awarding a Shiny Mythical encounter (Mew, Celebi, Jirachi, etc). Unova is the slated subject of the 2025 Tour in about 5 months, but Genesect, the only G5 Mythical with an available Shiny, is in Raids and thus can't be used for this purpose.
Assuming Go can influence any content plans or releases rather than vice versa, the logic is that they don't want something like Mythical Shinies 100% paywalled behind a money-only ticket in a Mobile game that takes significant time to complete (so pure collectors can't even hop-in, buy the Meloetta, and dip), so they want it available through a "main game" method so Go can drop it without being exclusive.
Abrupt timing of this specific one aside, I do think it's a pretty smart method. There's no timegate to it, but the amount of effort and work it takes to fill out a Dex in one Home Account is substantial enough to keep these mythicals fairly rare as special trophies.
