Chromium does not work with .local mdns/avahi name resolution

One way to get things working would be to install unscd or nscd, similar to what’s described here:

Accessing unix users and groups from a strict snap

Probably the only way you’re going to reliably access exotic user/group tables in confinement would be via a proxy like nscd (or an equivalent like unscd). It looks like any of the interfaces that end up doing #include <abstractions/nameservice> should grant access to its socket. One such interface is network, which you might already be plugging. I realise that using nscd can have some drawbacks, but it might be the best option here.

In that case, it was to provide a snap access to non-standard user/group NSS plugins, but the same should apply for host name lookup via NSS.
