hi julien,
about frequency rounding. if you are referring to the repr which is printed after ntwk, then yes it should be rounded, just for concision. this could be done more intelligently though.
about z0. skrf will automatically set z0 to 50, unless you specify what it is. this is not the same as z0-re-normalization, but you can do that as well. if you set you ntwk.z0 to 445, and then use ntwk.renormalize(50), then ntwk and ntwk_50ohm should match.
fixing hfss_touchstone_2_network()
would be much appreciated. it broke a while ago, because they changed their format, so you may want to do some version detection.
i think lack of standardized z0/gamma support is a major flaw in the touchstone format.

Hi,
New question : should Network()
detects HFSS touchstone files and parse it with its dedicate function?
The difference is that touchstone reading function used under the hood by Network()
does not parse the impedance and gamma, while hfss_touchstone_2_network()
does.

i think this would be a great feature.
