The apparent downside is that you waste disk space. OTOH: if you have “too much” swap (say 30GB on a 4GB system), then misbehaving apps will get an out-of-memory far later and that will slow down your system. Orderly behaving apps (without memory leaks) will simply not use it.
Should I increase pagefile size?
Increasing page file size may help prevent instabilities and crashing in Windows. However, hard drive read/write times are much slower than what they would be if the data were in your computer memory. Page file size should only be increased when encountering out-of-memory errors, and only as a temporary fix.
