After speaking with yourself and various people this week at CFCamp about this I agree, just think we need to give the community guidance on what will be supported by LAS as a "core" extension and what needs to be community driven.
Obviously the community can come up with any extension they like but in terms of ACF compat extensions, like
cfspreadsheet, I strongly believe LAS needs to provide this list.
Also, a central place for all these extensions to live, be searchable, easily installable, etc... is something else that either LAS needs to arrange and provide or task a community group to do. Before adding this thread I had no idea there was a already a Lucee
cfspreadsheet extension available out there. Can't say I had particularly looked, but if there was a central location I would be inclined to review it regularly for new additions and would probably have then come across it.
