My reasons:
- You get what you ask for:
  c++11 is c++11, not c++14 or c++20 (why would 42 mean 75?)
- You ask for what you want, not rely on internal config logic:
  min-c++11 means c++11 or above
- You don't get more than you ask for, c++ versions are not inclusive
nor incremental, semantics change and suff gets removed too sometimes:
  max-c++11 means c++11 or below
- If you want features as they come in, fire and forget: c++latest
