Things can change, they may have scrapped the plans to add 64dd support/transfer pak support when they decided to drop support for the wii u, and the rare games would probably be difficult to wrangle the permissions to release now that MS owns rare and EA own the 007 rights, the inis built in were probably just devs pitching the games seeking permission from the rights holders or simply devs playing about during development trying out various games without any intention of them ever being publicly released (especially with rare already releasing rare replay on the Xbox one)
And the emulators are obviously part of a bigger project of Nintendo developing their own emulators for all future consoles, so while we may not get any more new wiiu vc titles, development of the emulators will no doubt continue on the switch
