Additional Context

I downloaded this version from jenkins branch feature/extensions latest

Hot loading has (I believe) never been supported so this is more a feature request. Also I assume you meant 1.19.10 for the version?

[TypicalShavonne]

yea, sorry, i fixed it

I cannot say whether or not this will be added to Geyser. However, SessionLoadResourcePacksEvent is available within the geyser api, allowing developers to choose which resource packs a client should be sent on the fly.

You can use /geyser reload to reload the packs that Geyser reads from the pack folders. Hotloading resource packs from the packs folder can't be implemented, as that could result in a multitude of issues, such as an interruption while a pack is being sent to the Bedrock client.
However, #4205 will implement hot-loading for resource packs specified via url - as Geyser will then be able to provide a cached copy of the pack if the download fails.
