My guess would be a fairly poor performance on both a standard multipass and capacity tests... vs regular filters Of course the manufacturers know this and that's why those companies use all the tricks to avoid apples to apples comparisons with "regular" filters. I don't necessarily hold that against them... as long as they state the designed purpose of the filter, racing and high performance. And that's how you have to (should) look at them.
There are exceptions. Doug Hillary ran mesh filters on some OTR trucks in conjunction with centrifugal bypass (very fine filtration) and had good service. Makes sense. The mesh catches the chunks (say 35 um and up) and the bypass gets everything else down to submicronic. You then have maximum flow on cold starts and elsewhere with very no bypass or even much chance of the pump going into relief. That's a scenario that could work but it might not be the most practical solution for all.
But a mesh filter alone??? Not on my daily drivers.
