Pardon me playing semantic games:
I'd say there are not many things that DEMAND that amount of memory, never mind needing any swap.
I have a Firefox heavy, Thunderbird heavy desktop on 8G that doesn't go to swap. it doesn't go to swap because I've configured my VM not to swap unless it is absolutely necessary. As it happens, my swap is on rotating rust so its slow and any swapping will sow the system down, so the adage is "don't do that!" If I had a SSD? well, it's clear that I don't NEED to swap so why would I degrade a SSD by using it for swap when I don't swap in the first place?
This is not correct, but it is a common misconception. Your system will have less free memory and less memory used for buffers/cache. A machine with a certain amount of ram and the same workload performs faster with swap used than without. About using SSD for swap, it is not currently a concern: SMART Attributes Data Structure revision number: 1 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 9 Power_On_Hours 0x0032 097 097 000 Old_age Always - 11291 ******* 12 Power_Cycle_Count 0x0032 099 099 000 Old_age Always - 942 177 Wear_Leveling_Count 0x0013 098 098 000 Pre-fail Always - 22 ****************

Your Thunderbird/Firefox are not that heavy.
