My 1090 came with a tool kit that will take care of all trailside stuff, plus I've added a plug kit and small compressor.Edge case anecdote here:
My buddy rides a 1290 Adventure R and he dented a rim out on the trail. Tubeless wheel. Wouldn't hold air.
No problem, I carry spoons and a universal 21" tube. So we go to work taking the wheel off, removing the tire and... *screech*...
TPMS sensor in the wheel requires tiny Torx heads to remove, so you can poke the tube's valve stem through the rim.
I didn't have this small Torx head, but thankfully somebody else in the group did, so we were able to remove the TPMS sensor to stuff the tube in the rim.
Moral of the story: don't do a thought experiment in your head to populate your toolkit. Actually perform the repair from start to finish beforehand, so little gotchas don't halt your field repairs.
Decades ago I switched the cheesy JIS screws over to socket head. Then didn't include the allen wrench in the toolkit. On my first Ride for Sight I needed to open the clutch cover and had to borrow an allen key from a Harley rider., allen keys and

Did they stop including a tool kit on the 1290 or did he just not take it along?
