The biggest issue is that no one really understands what happens :-(

At first, MiKRO experienced crashes (before main ?) when running 
programs using nearly all the available TPA memory. So he added a nice 
message, and he increased the size of the preliminary stack.

Then Keith experienced problems of corruption of very long command lines 
(more than 2Ko) on ar or ld. I seems that the MiNTLib startup code use 
more or less the same memory area for the preliminary stack and the 
parsing of the command line.

Keith and Alan reverted MiKRO's patch, and everything went OK again.

Memory management is critical, especially in a multitasking 
non-protected environment... So it is probably better to do what you 
suggest - reverting to the original preliminary stack (while keeping the 
nice message ?).
