Uvdin Dechol doesn't apply to anything you decide to apply it to just because you're not used to see people doing it on shabbos. This has been discussed numerous times when new technologies came out. Here's a list of a few that come to mind that some poskim tried assuring due to them being עובדין דחול but eventually people got used to it and today nobody thinks they are that.
Shabbos clocks
Putting gas into seltzer
Pushing a carriage where there's an eruv.
According to most poskim, in order for something to be prohibitted for being uvdin de'chol it must be one of the following two things, 1) It should be something that involves טורח גדול, such as carrying very heavy non muktza items from one house to another, exercise according to some, or 2) it should be something that there's a חשש that it can come to a מלאכה דאורייתא.
