Yes, Jakub. I have reviewed net-shapers and noted that it is not
integrated into the kernel like tc. I mean there isn't a standard,
general-purpose command for net-shaper in Linux. It is used by other
tools or potentially device-specific drivers that want to leverage the
NIC's hardware shaping capabilities.
To configure shaping with net-shapers, users would need to execute a
command similar to:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/shaper.yaml
--do set --json '{"ifindex":'$IFINDEX',
"shaper": {"handle":
{"scope": "node", "id":'$NODEID' },
"bw-max": 2000000}}'

Given the simplicity of code implementation and ease of use for users in
writing commands, I opted for tc-htb.
