in the US at least, individual (universities, schools, departments, degrees) have pre-existing Officially Sanctioned Templates For Theses, and normally failure to comply with them means your document isn't going to be accepted until it's reformatted.
For example, one of my degrees was awarded in 2016, and the version history of the thesis template I used goes back to about 1988, complete with commented out lists of contributors and notes to future generations.
