Multiple firewalls from different manufactureres

Hello Group,In the past, I used to hear the recommendation that an internet facing firewall setup should include at least 2 firewalls from different manufacturers. The reasoning behind it was that if you had a fatal vulnerability in one of them, one that could enable an attacker to "own" the first, the second one will resist a similar attack.
Today, when attacks are shifting towards using the already open ports on the firewall, at the application level, do you think that such a setup is still mandatory and/or recommended? Do you see such setups implemented? Or does most setups include a single FW with multiple DMZs, connected directly to the internal network? Perhaps the screened subnet variety with 2 FW, but the same brand, is the most popular?
