When manually modifying links we found that t (type) and z (zoom) no longer seem to have any effect on the resulting map.

Additionally, per Google's own AI-generated result...

Google Maps uses standard ISO 639-1 two-letter codes for most languages, and occasionally includes a regional suffix for variants:

  • zh-CN – Simplified Chinese
  • zh-TW – Traditional Chinese
  • pt-BR – Brazilian Portuguese
  • en-GB – British English

While we doubt passing BCP-47 language codes are an issue, it seems noteworthy.

Passing only q (query) might be considered since Google presumably detects users' preferred language automatically.

Thoughts?
