Thanks for the warning.
The default delay value is 50, which means 50 centi-seconds, which
equals to toggling every 0.5 seconds, which gives 2 Hz.
On my laptop it takes even longer than 0.5 seconds for the default value
to toggle (twice a second).
The above UK site mentions:
Most people with photosensitive epilepsy are sensitive to 16-25 Hz. Some people may be sensitive to rates as low as 3 Hz and as high as 60 Hz.
Nevertheless the user can still inflict some damage upon him/herself by
changing the delay parameter, or tuning/modifying the software, their
computer, or whatever.
My gut feeling (legal advisor) says it's better to withdraw any patch
for any blinking whatsoever, due to the way the US legal system
regarding injuries and lawsuits functions.
Bear in mind that the upstream pcb repository resides on US soil.
3 Hz is just to close to 2 Hz for me to feel comfortable.
Put in other words: risk = probability * effect --> I take zero chance
and rather have no effect.

pcb blinking diff
Status in PCB: Printed Circuit Board CAD package:
The current pcbdiff tool uses the colours red and blue to mark the
differences between two pcb files of the same sizes (width and
Elements common to both pcbs are presented in grey shades.
The colours red and blue can make it difficult, if not impossible, for
people impaired with a colour vision deficiency (red/green,
blue/yellow or total) to distinguish the differences between the pcbs,
thus rendering the tool less usable.
By alternating showing the first and second pcb ("blinking") in grey
shades, the differences between both pcbs can be seen without colours
or the ability to perceive colour.
