item tooltipParams Tinker id

I found an extra undocumented field on the tooltipParams called 'tinker'
Seems to be engineering tinker effect

"back":{
"id":70555,
"name":"Vicious Gladiator's D#%@% of Diffusion",
"icon":"inv_misc_cape_16",
"quality":4,
"tooltipParams":{
"enchant":4096,
"tinker":3605
}
},

tinker 3605 is: "Reduce your falling speed for 30 seconds"

Any plans on exposing an API to look up these id's? Or include the text in the json? I know the text shows up on the armory page for characters
