Let me clarify my point a bit: If someone starts out making music now, they should be starting with the 64-bit version of OpenMPT (32-bit will die at some point, if you want it or not), and thus if they are just starting out with plugins, I think they should use modern plugins that have a native 64-bit version and that are DPI-aware so that they run well on modern high-DPI screens. The plugin bridge more or less only exists as a temporary solution for people who want to use these kind of plugins that they have grown used to, but in the end there are many disadvantages with this solution (most notably every bridged plugin introduces latency, and the plugin bridge isn't perfectly stable).
Old VST plugins are the main reason why OpenMPT isn't DPI-aware by default and looks blurry on high-DPI screens. I could make it DPI-aware by default but then people would complain about tiny VST UIs. This is also something that will die out eventually, and for newcomers I'd rather like to point them directly at future-proof 64-bit and DPI-aware plugins that most of the time sound just as good as those old plugins (or better).
