In fairness, marcov is not the DOS maintainer, doesn't use DOS, and he has enough to do (work, FreeBSD, updating FPC mirrors).

But it does seem silly. It's like me saying "8.3 is good enough" (which it is), but nobody wants to use that when LFNs are available, certainly not marcov. ;-) But I guess it's easy to marginalize DOS when there are very few "GO32v2" users. Perhaps some of us need to benchmark build times with r5 vs. r7 (or even vs. HDPMI32). As for swapping, you can disable it (-s- or permanently via CWSPARAM or just use CWSDPR0).
