Ever drawn a symbol or footprint yourself?
It takes some time for the first couple, but after that you usually know what you’re doing and there is wizards to help you along with repetitive tasks…
All parts I use I have drawn myself and most of the frequent users do the same as by the time one has validated the work of others the work itself could have been done (and how you want it).
Also note, if you prefer atomic parts (symbol + footprint as one) that come with manufacturer part number (or your own internal procurement number) you have to run your own libraries anyway.
