I certainly can't speak for Buffer, but most companies use bonuses to account for this (for salaried employees). Having a tiered salary structure lets both the company and the employee plan for a base salary from year to year and provides opportunities to "move people up" as the progress through a career. Beware what you ask for: if you produce less value for the company in a given pay period, they should be able to pay you less! I think tying a base salary to performance creates a really unstable financial situation for the company and the employee.
