Description
Are there any plans to introduce a js_balancer function akin to balancer_by_lua_block found in the Lua Nginx Module (https://github.com/openresty/lua-nginx-module?tab=readme-ov-file#balancer_by_lua_block)? We rely on balancer_by_lua for dynamically selecting servers. For instance, we utilize server tagging across multiple upstreams and use variables as a switch to avoid selecting servers with specific tags during proxying. This balancer hook is highly beneficial. However, it seems that NJS lacks a comparable hook.
