You may not want to start having a section of defined terms, but MPLv2 has a definition of the term "Modifications" that seems to be what you're describing for changes:
means any of the following:
a. any file in Source Code Form that results from an addition to, deletion from, or modification of the contents of Covered Software; or
b. any new file in Source Code Form that contains any Covered Software.
With that said, while I personally don't have a preference wrt an open source license being file-based, there are certainly some folks who prefer a stronger copyleft. That might come up when you submit your license.
