Just curious, I've got 15+ years of experience I can put on there. If I simply listed the ones that I thought were most relevant to the position I was applying for, would you ask why there are gaps? For example - during the 2008 downturn, I worked a job that was not terrible, but used tools and hard skills that were completely non-transferrable to any job I've had since then. So I no longer put it on my resume even though I was there for 2 years. Would that two year gap over a decade ago be a conversation? Assuming of course, that I even put anything prior to 2010 on an application anymore. I guess for me - do you dig into every gap you see? Maybe they left under good circumstances and just don't want to list the job because they weren't proud of the work they did there.
