in my book quoting everything instead of dropping quotes is the better
option. While that policy adds more quotes, it prevents surprises like:

	$ yaml2json << EOF
	> countrycodes:
	>  - de
	>  - fr
	>  - no
	>  - pl
	> EOF
	{
	  "countrycodes": [
	    "de",
	    "fr",
	    false,
	    "pl"
	  ]
	}

And if you use the "only-when-needed" rule of yamllint you have to write
the above list as:

	countrycodes:
	 - de
	 - fr
	 - "no"
	 - pl

which is IMHO really ugly.

Another culprit is "on" (which is used e.g. in github action workflows),
so yamllint tells for example for
https://github.com/pengutronix/microcom/blob/main/.github/workflows/build.yml:

	  3:1       warning  truthy value should be one of [false, true]  (truthy)

and there are still more surprises (e.g. version numbers might be
subject to conversion to float). So at least in my bubble the general
hint is to *always* quote strings. Note that required: true is also the
default for yamllint's quoted-strings setting, proably for pitfalls like
these.

Best regards
Uwe
