Они только называются не «национальные» а visa with limited territorial validity (LTV), и это, вроде, не «рекомендация» а возможность, если какой-то другой member state имеет озабоченность лично о вас в смысле безопасности.

https://ec.europa.eu/commission/presscorner/detail/en/IP_22_5430 — «Under the EU visa rules, a Member State can also ask to be consulted before another Member State issues visas to Russian nationals, on grounds of threats to public policy, internal security or international relations. The consulted Member State can object to a Schengen visa being issued to a Russian national, on an individual basis. If issued, the visa would then be limited to the territory of the issuing Member State, and not grant access to the entire Schengen area.»
