Hi,
From the VisualGDB side, there are no limitations regarding the C++17 support. As long as you are satisfied with the level of support provided by the GCC version you are using, it should be totally OK.
The ‘experimental’ label was added to VisualGDB settings when the C++17 support was still incomplete in most of GCC releases and should not apply to the latest GCC anymore. We have updated VisualGDB internally to remove the ‘experimental’ label.
