As mentioned before that I started to see a good side of using Glide Tables instead of using Google Sheets in some cases, like some tables might be updated rapidly in real use. But this hunch always came a bit late; After a while of putting up so many relations & lookups & data templates, then I realized that this sheet might have less problem if I changed to Glide Table.
But this means a do-over with all the table setups, not to mention all data links on the interface will be cut-off which cannot be undone. All the interfaces will be gone forever.
To be able to change without losing all relationships between Sheets and interfaces could be a big feature. And the easier the migration is, the more people will be using your Glide Table (which will cost you much much less for API connectivity in a long run) for sure.
*** For me, I just need the structure & relations to survive the migration, because I will do this only during the development phase, not the production ones. So, the data could be omitted, which I think it might sound easier to you.
