I'm curious what will happen to the live channels if they'll just stop existing come March. Can totally understand your situation, similar one myself as my daughter loves Disney Jr shows and I've got all the MCU and SW films physically, only difference is I don't have any of the Disney animated movies so Life is an absolute goldmine, and hopefully Plus will push them all up to 4K, especially if it's just £5.The main draw to Disney Life for us was the live TV, tv shows, books and music. My boys love watching Disney Jr and Mickey Mouse Clubhouse. I have an extensive Disney/Pixar/Marvel/Star Wars collection on Blu Ray (viewed via Plex at better quality than DL) so access to Live TV and odd TV shows was the main draw for us. Fiver a month for that seemed worth it. The movies and 10% off at Disney Store was a Brucie Bonus.
Unless I'm given a very good reason to carry on if/when they stop DL in favour of D+ I guess my boys will have to quit rodent cold turkey.
