That's still a common and accepted way of doing the job.
If you have an air compressor, you can buy a tool that
screws into the cylinder hole and takes an air line, and uses
the compressed air to keep the valve up.
It's a lot faster to use than rope, but the rope is
still a good trick if you want to take the spring off
overnight or something to measure or get a replacement. Otherwise
a power outage on the compressor overnight could cost
you a head-pull!
(but the compressor is sure faster when doing
work on more than one valve)
