I thought I'd ask something that just occurred to me: Can lwIP's
implementation of malloc result in fragmentation of lwIP's heap?

If it can, than a system requiring 24/7 operation would be better off using
lwIP pools since they cannot fragment.
That's why I added the option for mem_malloc to use (multiple, different-sized) memp pools (added with 1.3.0, I think). We are only using lwIP that way. There are still some places where memory allocation can be improved in the stack, much leaving the heap for PBUF_RAM only.
