ABSOLUTELY!!!!!!!
I do NOT understand why people immediately jump on a 10.x.0 release, especially when historically, they've been pretty messy for people like us who dig reasonably deep into the printing subsystem only to find 'problems'.
At very least, get yourselves a standalone small disk/SSD and put the new OS on that and boot off it and then play.
I've been sitting on 10.10 for a good long time and just recently went to 10.12 (part of the reason is the complexity of running a Hackintosh)
YMMV
A lot of assumption in those "why do you upgrade" responses while knowing nothing about the poster and his motivations
Neither Op or me stated we "jump on new versions" un prepared.
nor do you know anything about background and reasons for upgrading
I have been in the systems administration and support business for around 25 years, so I pretty well know what to expect and how to keep my systems running and safe.
for the record I am not on *.0
Second, I have upgraded in order to test for issues and have taken the precautions needed to go back if necessary
If everybody waits for the >3 or later release, there will be no bugs fixed, and it will be as unstable as the *.0
For me with the epson 2880 being an old beast with a probably substantially reduced installed base it might very well be nobody finds out about the issue, and if they do they might never flag it to epson/apple and stay on older OS versions. Therefore I want to test this asap. knowing about a potential effective end of life situation or supportability issue earlier on is better risk management than waiting it out and find out you have an issue when you must upgrade because of End of support issues on your Operating system.
would be a pain to have to introduce any issue or problem like Posted with a preamble like this both for poster and readers

I'll further keep this thread on topic as all this will not help the OP or others in any way.
