Comment (by birgire):

 @jonoaldersonwp thanks for clarifying that. I guess it would be like
 running both the native way and a JS fallback, yeah that was my worry. I
 will just try this out when I can :-)

 I assume there might also be content cases like:

 {{{
 <img data-no-lazy="1"
 <img class="skip-lazy"
 ...
 }}}

 i.e. if the user has explicitly set the content images to not lazy load.

 I think those cases should be respected, if possible, so that they would
 not be lazy loaded regardless.

 So in addition to defining a suitable flag to avoid this, the existing
 flags out there, should be respected, if possible.
