How common is that today? In Austria most landlords stopped offering indefinite leases a long time ago, and are instead renewed every 3 years or so when they can increase your rent or kick you out.
Or if you have an indefinite lease it's automatically indexed by inflation which screws you big time if your wages aren't keeping up. The only indefinite lease currently in existence without inflation indexing are very old contracts who got grandfathered in but no landlord is crazy to offer that today anymore.
