It is normal for scripters to make assumptions about how features work and to create scripts that parse the servers.ini, mirc.ini, and so on. It's not ideal because formats can change but it does seem to be common. That is why backwards compatibility is important.
In this case, there are no plans to change how mIRC uses INI files for the servers list or other features.
That said, I looked into the idea of merging of new and old servers.ini files about twenty years ago, going as far as creating an interface for it. In the end, I decided it was too complicated for regular users, and messy even for techies.
