[dev] [horizon] [tc] [release] [PTI] is tox a requirement even if tox is not used?

Hi, # I am not sure [tc] and [release] tags are appropriate. Horizon team maintains xstatic-* repositories [1]. We have a question on the need for tox.ini. Can we drop tox.ini completely considering the situation below? These repositories do not depend on 'tox' on testing from their nature of re-packaging JS module in a python way. In addition, there is no document provided. The current PTI mentions only "tox -e docs". # Previously PTI required "venv" tox ini but it is no longer mentioned.
