The following command is on how to apply hflip_vulkan filter:

ffmpeg -init_hw_device vulkan -i input.264 -vf hwupload=extra_hw_frames=16,hflip_vulkan,hwdownload,format=yuv420p output.264

What is the point of this class with its empty options?

The AVFILTER_DEFINE_CLASS needs the hflip_vulkan_options and the reason why it's NULL
is that the most other filters do it like that.

And why do you add an AVClass at all?
(The reason that there are some filters with AVClass and empty options
is a bug in avfilter_init_str() which errors out when given options for
a filter without AVClass, although it is perfectly fine to set options
on a filter without AVClass, namely generic AVFilter options (this is
important for e.g. framesync filters, but not for this filter here).)

Simply I think it is a convention. Yeah. It's not needed at all. I'll remove it and update later.

Do not do it if it breaks timeline support.

There are abandoned patches of yours that resolved this.
