Agree. Remembering that this "new modern" shocks have a piston separating oil and gas. So, one hole for oil and gas does not work any more.
If a shrader valve is too big for your shock, you can use a KTM M5 style bolt (neoprene seal and needle system) witch require a special inflating device.
I have a Sachs shock on my 07 Gas Gas. It doesn't leak but needs the oil changed. I watched your video and was thinking I can take it apart just enough to change the oil, not take it completely apart like you did. A couple of questions: can I release the pressure without drilling a hole? Are your repressurizing with just air? Thanks.
You need a hole to pressurize the shock after reassembly too.
Air is 80% nitrogen. Not ideal but work (on trials) just like mountain bike and downhill shocks because shock does not get too hot like on a enduro or MX

It can be done with good results if shock hasn't wear inside.
