The OP's discovery of no cross hatch after so few miles raised a flag, and prompted a question. I understand that many (perhaps most) folks would choose to just leave it alone, especially if it required having to pay for the service, but for the do-it-yourself types that enjoy putting in the wrench time, its worth doing in my opinion.
There is a process called nitriding, that surface hardens steel. This is applied to piston cylinders to make them wear far longer than steel untreated. Hone marks in such cylinders last a very long time, with reports of 75,000 miles and the pattern can still be seen. The nitriding process is only a surface treatment. Boring a cylinder will remove all the nitriding, leaving softer steel to wear faster than it did when new.
It was my understanding that Honda had their cylinders nitrided. But, I don't know that for certain. If true, it would well explain why the cross hatch is not there, after an 836 kit was installed.
There is also the question of how deep the hone scratches were when new and how deep the scratches were made during the kit install. Clearly deeper scratches would remain longer in a nitrided barrel, than shallower scratches made during the kit install.
With a harder surface, more aggressive grits can be used during the cross hatch process. You wouldn't want to use such an aggressive grit (deeper scratches) with an un-nitrided barrel.
IF the barrels in question are wearing too fast, it would be measurable while there is access to them. Roundness, metal loss, and cylinder taper can be determined before reassembly. If determined to acceptable, and the rings weren't passing oil and holding compression before disassembly, put them back the way they came apart, I say. It's what I would do, anyway.
