setPluginData 100kb size limit now being enforced

I've encountered a blocking error in our plugin development environment that began approximately one week ago:

{
    "message": "in setPluginData: This pluginData entry exceeds 100 kB per entry limit."
}

While this 100 kB per entry limit is documented in the official setPluginData documentation, it wasn't actively enforced until recently. Our plugin functionality depends on storing entries larger than this limit.

Questions:

1. Will this restriction be enforced in the production environment as well for the existing plugins?
2. If yes, what is the expected timeframe for enforcement in production?
