Inkscape might use SVG as its default format, however this SVG's contains some additional SodiPodi/Inkscape additions that can be troublesome if you want to import the SVG into some other application.

Inkscape 1.0 uses GTK 3 which is sluggish and slow for low spec systems( eg. ARM, Celeron, Pentium, Core-i3, Ryzen 3 or Athlon ) compared to previous versions.
Con Buggy
Application is often buggy so it happens from time to time that the popup / right-click menu won't close and stays open. It crashes also sometimes randomly. This makes it almost unusable for productive / business use.

0,0 coordinates begin in lower left corner, not upper left corner as SVG standards define in Inkscape 0.92.x.
It seems this is now fixed in the 1.0 beta 2 version of the program.

Con A toy for facebook-ist enthusiasts, not for professionals
It's a Linux niche mumbo-jumbo, same as GIMP for raster edit .

Software is based on GTK, so it might not integrate well in non-GTK environments. It also requires many dependencies on those non-GTK desktops. It also adds dependencies to GTK-environments since it is written in C++ which requires the gtkmm wrapper/interface.
Con Mac version does not look as polished as its versions for Windows/Linux version for the 0.92.x version
It seems that Inkscape 1.0 beta 2 for Mac got some needed attention and it looks a lot better with dark theme support. native DMG installer and they got rid of X11 which is great.
