Many of the gimp filters in 2.10 have been given new names and recategorised. If not left out altogether - there is a search function for them too. Unless they have been left out because of being "not worth leaving them in" you will find them. Unfortunately the site we used to go-to for scripts etc (The link above goes to a non existant page). has shut down - no one has been maintaining it for a long time. Someone may have a filter/script/plugin your looking for and hopefully Lyle will pop up and tell you if he has the other filter too - I assume you have tried the search function in GMIC?
Just a thought. You may find them through Wayback Machine. - archive of older sites.
