I'm guessing because it exercised your "shiny new" subroutine?

Peter,
Nice move on the AUR(34) using the mixed internal/external sis.
I usually check for AURs early in my sequence and also noticed the AUR(34) but used all internal sis where (9)r46c3-(9=4)r2c3 making r2c3=4.
A couple of BUG-lites are in r89 that provided useless deletions, but were interesting to work with.
I also made a second pass and found this two stepper.
(8=6)r6c7-(6=1)r6c5-r1c5=r1c2-(1=9)r4c2-r4c8=(9-8)r6c8; r6c8<>8
anp(34=6)r46c9-(6=1)r6c5-(1=7)r1c5-r2c4=r2c8-r3c9=(7-4)r8c9; r8c9<>4=7

Yes, my "shiny new" subroutine had a ball with this puzzle.
| Code: | after basics
+-----------------------------------------------------------------------+
| 3 17 6 | 5 17 8 | 4 2 9 |
| 14 5 4-9 | *16+7 2 *16=9 | 3 67 8 |
| 8 79 2 | 3467 3679 3469 | 1 5 67 |
|-----------------------+-----------------------+-----------------------|
| 6 1-9 *34+9 | 2 8 5 | 7 149 *34 |
| 14 8 7 | 9 136 1346 | 5 146 2 |
| 5 2 *34+9 | 146 16 7 | 68 14689 *34+6 |
|-----------------------+-----------------------+-----------------------|
| 7 6 1 | 8 4 2 | 9 3 5 |
| 9 3 58 | *16+7 1567 *16 | 2 4678 467 |
| 2 4 58 | 367 35679 369 | 68 678 1 |

Single-stepper:
| Code: | (9=7)r3c2 - (7=6)r3c9 - r6c9 =UR= (9)r46c3 => r2c3,r4c2<>9
|
Two-stepper:
| Code: | r2c9 2-String Kite <> 7 r8c4
(9)r2c6 =UR= (7)r2c4 - [ (7=1)r1c5, (7=6)r2c8 ] - (16=9)r2c6
|
I found a single-stepper variation on the two-stepper:
| Code: | (9)r2c6 -or-
(7)r2c4 - [ (7=1)r1c5, (7=6)r2c8 ] - (16=9)r2c6 -or-
(7)r8c4 - r8c9 = r3c9 - (7=6)r2c8 - als(6=9)b2q246
