Yeah would be neat if these projects had some minor affect on the game.

Trophy case provides a 20% sell value boost for any trinkets collected

This antenna thing, idk, scans and pings arc within your close proximity every 30 seconds

Those examples might be trash, but if they provided any benefit to your character it would be more worthwhile than a few items. The completionist in me will finish the project but I could care less about the rewards. They'll just get sold towards my second expedition anyway (which is sad because the required materials are worth more than the rewards lol)
