Those weren't the only problems with VLIW (and more specifically Itanium-type VLIW).
Recompiling and increased code size would've been fine if that were the only concerns.
The big problem is that so far, in general purpose workloads (the type with heavy control flow and gnarly memory access), VLIW was never able to match OoO in performance in terms of extracting enough ILP.
