Survey: Frontend Language Support

Dear @openPMD/general-contributors,

this issue is pinned to keep track of your needs for our reference API in terms of minimum supported language features.

So far we support Python 3.6+ and C++14 or newer. But as compilers and languages progress, we would love to drop old language revisions in newer releases to keep maintenance at a minimum and make use of newer language features in public interfaces. Please vote in the following comments according to the **minimum requirements** you have in your downstream code-bases. This will help us to plan potentially breaking changes with minimum hazzle.

Voting in the C++ and Python frontend will help us to ping and interact with you in case we would like to drop, e.g. C++14 bindings (for C++17 and newer) or older Python bindings in the future.

Voting on new language bindings does not implicate someone will find the time to provide such implementations, but it potentially motivates volunteers to step forward and add further bindings or share their own implementations where needed.
