There seems to be a misconception on the part of the devs that allowing too much swap will result in machines under memory pressure suffering worse than if they simply ran out of memory and the kernel's OOM killer rescued the system. Running out of memory is almost *never* better than hitting swap. Depending on the application, it is possible to swap out vast swaths of system memory to make room for temporary spikes in memory allocation. It is also customary for the kernel to swap out about 1GB of memory that will most likely never be accessed again after boot. This cannot be done when the max swap is 1GB. Factor in fast SSD's and VNME's that come much closer to the performance of RAM, and a system can remain quite usable even if it should develop a swap storm. The bottom line is that this should be a user-tunable in the installer and not something users have to resort to swapfiles to work around.
