Layer locking helps to control the design, so managing this option gives peace of mind not only to the designer, but also to the editor, as it allows him to modify only what is necessary without thinking about spoiling or damaging the template.

On the other hand it is very important as creators to be able to share the templates through a link and that these can be modified without altering the initial (as in Canva or Corjl) we can also limit the number of downloads and not allow that template can be shared by whoever modifies it, it would be great if adobe included these options, as they would be a plus and a great, great value as designers.
