"Taxpayers both in the U.S. and Europe should be righteously angry at Congress, NASA and ESA for not appropriating the funds and designing the projects necessary to hold to the original return date," Hubbard concluded.
Hear, hear!
But even if a sample grab partly mirrors the collected martian meteorites we have, it and its undisturbed nature will add to the whole.
FWIW, recent science on martian meteorites: Despite some of the rock ages they are fairly young ejecta from an estimate 5 impacts on Mars so samples a small diversity.

That they are young ejecta is consistent with recent science on asteroid meteorites, they too are sampling a small diversity at recent times since the fragment population is eroded relatively quickly.
Here we show that approximately 70% of meteorites originate from three recent break-ups of D > 30 km asteroids that occurred 5.8, 7.6 and less than about 40 Myr ago.

Find a money reason to go. Then all want to go.
SpaceX and Blue Origin is betting on money being provided by a smaller fraction of colonists (Mars respectively O'Neill habitats), which will reproduce and grow. Assuming they can make space launches cheap enough.
However, there is no Earth analog for such colonization, it was driven by looting indigenous resources. Antarctica science and tourist habitats is the closest analog and its population not growing at colony speeds.
We'll have to wait and see what happens.
