Make inline=False the default behavior for hv.extension

[hoxbro]

I want to start a discussion about making inline=False the default behavior for hv.extension in notebooks.

In my opinion, it would be better to have inline=False as the default behavior. I think inline=True was meant for airgap environments and not something most users need.

It will reduce the file size significantly. A quick comparison with inline=True and inline=False shows that the file size is 18 MB vs 45 KB, respectively.

Some problems that have also come up recently where it is not obvious that it is related to inline=True:

1. Plotly cannot load in VS code with inline=True:

   • Holoviews not showing plots with plotly backend in vscode #3733 (comment)
   • Plotly backend not working in VS Code notebook (but plotly express works independently) hvplot#1071

2. Bokeh gives Javascript error in Jupyter Notebook:

   • Javascript Errors when setting Extension in Jupyter Notebook #5699 *

*) This seems to have been fixed by not loading MathJax by default because of holoviz/panel#4895, but it will come back with #5729.

As this is a breaking change, it should be implemented at 1.17 as a minimum.

Sounds like a very good idea to me 👍
