Should a client own or manage their Avenza Map?

If I create a print map for a client, and upload it as a free Avenza Maps version, should I upload it to my Map Store or suggest that the client sign up as a Publisher and upload the map themselves?

For my clients who pay me to make a print map, the Avenza Maps version is a secondary benefit to them. I think they would not want to sell the map but instead have it available for download along with distributing their printed map.

Can a map I upload to my Map Store account later be transferred if my client wants to take over management of the Avenza Map version? This situation would also apply if a Publisher quits the business. How to they distribute their inventory of maps?
