You're right of course, but the list isn't just useful for autocomplete, so to write faster or less, but it's a tool for finding "what was that function called?". Or just to browse which functions are available to find a suitable one. Or to find an idea, e.g. which methods has the control X? ... But I digress ;-)
Maybe you already have a sensible limit in mind. If you're looking for a sensible limit, check it out at Delphi, for example. In Lazarus, I just looked it up, it's for "Application." almost 300 elements, for "Form." over 400. I'm happy about any increase you choose! And I think other users are happy too! :) -- <https://forum.pspad.com/read.php?2,75152,75170> PSPad freeware editor https://www.pspad.com
