The planning strategic tools are prevalent in the industry. They are the accepted ones, and the people with the credibility of the industry to talk or work on it belong to the Big-4 or similar.
On the other side we have emergent frameworks, models and tools. They are small niche and not known by companies.
Companies that know these tools basically ignore them, they are not going to expose themselves into using it.
Wardley Mapping belongs to the low visibility side of the map. Just go to Google trends or you favorite data source and compare with others.
I did here a small and basic data research, and the invisibility of Wardley Mapping is a fact.

All this is a draft, or a starting point.
Right now, we are going to do an experiment trying to see how to gain visibility pointing to the benefits of using Wardley Maps in combination of SWOT and PESTLE.
Why these 2 tools? In terms of data I have gathered they are the most present.
Any constructive feedback is welcome.
