For now it should work but it will have an increasing likelihood of breaking with every future Android Update.
Migrating to Mihon now is recommended, one of the devs worked on Tachiyomi and for now the code is almost identical which allows easy migration via a Tachiyomi Backup.
Migrating in the future might be more difficult because incompatibility between Tachiyomi and future versions of Mihon could mean Backups from Tachiyomi cannot be restored by Mihon.
