Is it permissible to compete in Masters events while using optical display devices such as Finis Form? (On a recent SwimSwam interview between Mel Stewart and Nathan Adrian, Mel said they were permissible in- because they did not communicate with others?)

Hmm. They way those rules are written, I’d argue that my use of optical display goggles was for “data collection” and not to enhance my speed.

Disagree. The use of the qualifier "sole" before "purpose of collecting" invalidates the argument. It can't be used for simultaneous feedback and data collection. The sole purpose language is to allow the use of a ring on your finger which records the biometrics, to be read later. Katie Ledecky is a spokesperson for that item.
