Not undesirable at all, just that in getting a patch your community generally expects you to go to billets that you'll go do things that require patch level knowledge. At least in MPRA per our WTM if you get a patch you're required to do a shore tour in a WTI billet (aka MPRWS, WTU, NSAWC, NMAWC, some VP-30 billets, or some forward CTF billet). For MPRA if you did a WTI shore tour you can be eligible for the super JO gig (now called SMTI) provided you meet some other requirements. We only have 12 squadrons so less demand for numbers of super JOs vice boat orders, so it's pretty competitive to get.
