Hi Pakito,
Yes fuse directionality should be explored by everyone who has taken the time to upgrade their fuses and with high resolution fuses even more so.
The reason I bump my fuse ratings up slightly is that since most high end fuses are on the costly side, as compared to generic hardware store glass fuses, I want to increase the headroom margin so as not to risk blowing a fuse in the event that the circuit designer chose to be on the conservative side of current protection and to also provide circuit protection in the event that a circuit malfunction does occur.
Hope this helps.
