why would there be 'thousands' of new timezones?
Because, if one defines a "region" to be "a set of geographical locations where civil-time clocks have agreed since standard time was introduced", there must be thousands of such regions, each unique as far as UT-offset history goes. Shanks identifies over 300 such regions for Indiana alone, and most likely he missed some. (Again, I'm ignoring UT offset before standard time was introduced, and I'm ignoring the date of transition to standard time.)
