I support this proposal.
I have also thought the requirement to use the Czech or German gender suffix "regardless of time period or what is written in the parish record" was artificial, and not necessarily reflective of the community at the time the registers were kept.
This may be reflective of current practice in the Czech Republic, which may have, at least in part, origin in Czech nationalism in the latter 1800s, the advent of Czechslovakia in 1918, and the expulsion of the German ethnic group after WW II.
Clearly, the Czech nation has evolved. Our practice should follow the nature of the country taking into consideration both the location and the time period.
