That is essentially what's driving the popularity of smallsats and megaconstellations. Since launch costs are dropping and flights are becoming more regular (eg SpaceX's transporter flights, where the rocket flies regardless of payload readiness and anyone who wasn't ready just moves to another flight, eliminating the main issue from other rideshare arrangements), it's potentially cheaper to make more replaceable satellites. So far this mainly applies to Earth observation and internet constellations. This doesn't really carry-over to large projects like JWST yet though.
