That is certainly one approach, and if Canonical is going to provide some general support for finding snaps that support particular hardware (not just printers) then it makes sense.

That said, the number of printer applications is not likely to be huge (LPrint, hp-printer-app, and ps-printer-app make 3, and potential future HP-LIP and Gutenprint printer applications make 5), so even if you just maintained files with the latest "app-name drivers" output you'd be able to do a good job of mapping printers to printer applications.

Remember, Printer Applications are addressing a short term (~10 year?) need to support legacy printers, at which point the primary users will be "experts" that wouldn't use the default printer application/IPP Everywhere support anyways.  New printers almost universally support IPP (the outliers being for "experts").
