No, when I have ridden road bikes with a 1x drivetrain and a standard chainring, I have not experienced a frequency of chain drops that I considered problematic. Generally I think the bumpier one's riding the more likely the chain will drop. Generally I think the wider the rear cassette and the shorter the chainstays the more likely the chain will drop.
My general recommendation is use what you have or use what you like. If the frequency of chain drops is a problem for you and you want to fix it, then add a mitigation. For your case, you used what you wanted to use, and you currently don't have a problem, so don't fix it. For the OP, who already has a 42T ring, I recommended that he give it a shot, and I repeat: give it a shot. If there are no problems, don't fix them. The mitigations that I've seen and heard of people using include:
narrow wide rings
a dummy FD
a chain guide
clutch rear der
high chain tension (short chain)
stronger RD spring tension
sandwich of chainguards on either side (the old school cyclocross fix)
I think it would be wasteful to throw all those mitigations at a build before you even know whether you have a problem. My most recent 1x road build needed a new ring, and so I went ahead and used a narrow-wide ring. I can't prove I needed to use it. My most recent 1x cyclocross build was from the ground up, and I elected to use a clutch RD and a narrow wide ring. Whether I could have gotten away without either of those is unknown
