should there be a larger fastcgi buffer size in the default nginx config to avoid 502 errors

[ghost]

I recently had an issue in which ajax POST requests were getting a 502 Bad Gateway nginx error on Laravel Valet.

The nginx error logs revealed "upstream sent too big header while reading response header from upstream"

After seeing these related Issues, I was able to resolve it by editing the php block in valet.conf

1. Nginx / Valet - 502 Bad Gateway - upstream sent too big header  #890
2. Valet 2.0.3: 500 Bad Gateway (upstream sent too big header) #290 (comment)
3. 502 Bad Gateway - nginx/1.10.2 #269 (comment)

settings added were:

fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;

Configuring nginx is new to me, but seeing that this has happened before, my question is should the default settings of valet.conf have a larger buffer size to help other people in the future?
